Evented Actions will automatically dispatch a 'before' event passing. By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events. Optional arguments for the action fn. If not given, the normal args will be used to call fn.
If false is passed, the args are used but if the first argument is this instance it will be removed from the args passed to the action function. Returns a specified config property value. If the name parameter is not passed, all current configuration options will be returned as key value pairs.
Returns undefined if the property has not yet been initialized. Retrieves the id. This method Will auto-generate an id if one has not already been configured. Calling btn. Checks to see if this object has any listeners for a specified event, or whether the event bubbles. The answer indicates whether the event needs firing or not.
Adds a "destroyable" object to an internal list of objects that will be destroyed when this instance is destroyed via destroy. Shorthand for addManagedListener. Shorthand for removeManagedListener.
Removes listeners that were added by the mon method. Same as addListener with order set to 'after'. Appends a before-event handler. Returning false from the handler will stop the event. Same as addListener with order set to 'before'. Relays selected events from the specified Observable as if the events were fired by this. For example if you are extending Grid, you might decide to forward some events from store.
So you can do this inside your initComponent:. For example: this. Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'. An object which implements the destroy method which, when destroyed, removes all relayers. The handler to remove. This must be a reference to the function passed into the addListener call. The scope originally specified for the handler.
It must be the same as the scope argument specified in the original call to Ext. Observable addListener or the listener will not be removed. Important: Ajax server requests are asynchronous, and this call will return before the response has been received.
The options object may also contain any other property which might be needed to perform postprocessing in a callback because it is passed to callback functions. The scope of the function is specified by the scope option. Defaults to the configured url. Defaults to true. An object containing properties which are used as parameters to the request, a url encoded string or a function to call to get either.
The HTTP method to use for the request. Defaults to the configured method, or if no method was configured, "GET" if no parameters are being sent, and "POST" if parameters are being sent. Note that the method name is case-sensitive and should be all caps. The function to be called upon receipt of the HTTP response.
The callback is called regardless of success or failure and is passed the following parameters:. See www. The function to be called upon success of the request. The callback is passed the following parameters:.
The function to be called upon failure of the request. The scope in which to execute the callbacks: The "this" object for the callback function. If the url , or params options were specified as functions from which to draw values, then this also serves as the scope for those function calls.
Defaults to the browser window. The timeout in milliseconds to be used for this request. Defaults to milliseconds 30 seconds. The response text is retrieved from the document, and a fake XMLHttpRequest object is created containing a responseText property in order to conform to the requirements of event handlers and callbacks.
Request headers to set for the request. To prevent this, setting the Content-Type header to null or undefined will not attempt to set any Content-Type and it will be left to the browser. XML document to use for the post. Note: This will be used instead of params for the post data.
Any params will be appended to the URL. JSON data to use as the post. A raw string to use as the post. An array of bytes to submit in binary form. If binaryData is present, you must set binary to true and options. Gets the default scope for firing late bound events string names with no scope attached at runtime. Note that if the suspendEvent method is called multiple times for a certain event, this converse method will have to be called the same number of times for it to resume firing.
If events were suspended using the queueSuspended parameter, then all events fired during event suspension will be sent to any listeners now. See suspendEvents. Get the reference to the class from which this object was instantiated. Note that unlike Ext. Base self , this. After calling this method to suspend events, the events will no longer fire when requested to fire.
Note that if this is called multiple times for a certain event, the converse method resumeEvent will have to be called the same number of times for it to resume firing. Same as removeListener with order set to 'after'. Same as removeListener with order set to 'before'. Destroys a given set of linked objects. This is only needed if the linked object is being destroyed before this instance.
Adds new config properties to this class. This is called for classes when they are declared, then for any mixins that class may define and finally for any overrides defined that target the class. Class optional. Pass true if the members are private. This only has meaning in debug mode and only for methods. The new method name, or an object to set multiple aliases. See flexSetter.

Panel', alias : 'widget. Actually, the version I use is Ext JS 6 but I think the solutions based on previous versions do the work as well. Online demo here. You will need to use a form if you want to submit the file. Even if you want the button to be in a toolbar, you can enclose it in a form and it will still look like a normal toolbar button you will need to specify the proper ui config for this. While I agree with scebotari's answer that in your case embedding a form in the toolbar is probably the easiest solution, for the sake of answering the original question:.
If you really cannot or do not want to use a form and you're not limited regarding browser support, have a look at the FileReader. The idea is to read the file contents on the client side JavaScript and then send the data using a regular AJAX request. You are looking for the event change on the fileuploadfield.

Ajax Clearly, I have not understood the correct implementation and how to synchronize a form field component with an ajax call. I am using the ajax call to pass the necessary headers also, Content-Type and Content-Disposition. Apologies, if I have not formatted something correctly or made this too long. Regards, Jai.
